Attached Link: Grass makes the difference.

Spit...

:I disagree about the terrains in Bryce very strongly. If you want one terrain for your entire world then go with Mojoworld (great) or Terragen or somesuch.

I don't want to make entire world terrains in Mojo or Terragen, I want to do it in Bryce. Bryce has ALOT of advantages over those programs. One ofcourse is the treelab.
But the terrainsystem in bryce is just outdated and very old. Making large landscapes in Bryce is barely possible. All terrainbottoms must be leveled for the terrain to be seamless. Normally, landscapes in Bryce looks nothing more than a cluster of seperate terrains. Mojo has a huge advantage on this part.

: (1) it's easier to get more interesting textures by using several terrains. One terrain over your entire world and you're stuck with one material and/or post processing in Bryce.

Terragen has kind of a problem with this, although the lighting in that program provides with great diversity.
Mojo has a great way of distributing it's texture areas, unfortunally Mojo seems incapable of using textures (judging from the gallery). Maybe in a later version.

: (2) It's nice to build your features in your world instead of relying on one perfect heightmap. You want a cliff over there? Use a separate terrain and have total control of it.

Yes, this is an advantage. I would like for the old terrains to still be available, but I would also want a planetary option. In order to get several terrain-objects look seamless you must either hide the point where the terrains intersect, or have the terrains leveled at 0 at the intersectionpoint.
You can't expect to create the kind of vast landscapes Mojo has using terrainobjects.

: Seems to me that you want it to create worlds on the fly to save time, wich...ofcourse...is fine.

Not just saving time, saving sanity aswell. :-)
The problem here is that making changes on small peices of the landscape (terrainobjects) at the time, makes it more difficult to control the entire landscape.

: I on the other hand like to have total control of every single detail in the scene and Bryce never failed me there.

Same here. Bryce is easy to work at and effective when it comes to small scale working, but it doesn't cut it in the large. And as I've understood it, that was what the program first was intended for. A landscape creator.

: Besides that..I dont think there is an application that truly fits anyones wishes or needs.

It seems that some apps has some options/tools and others have other kind of tools. The problem is that they aren't all in the same utility. Mojo makes great landscapes, Terragen makes great skies, Worldbuilder makes great vegetation and bryce makes great alot of things.
I would think that it would be a too big step for bryce to realize and adapt the qualities of those other programs. Atleast some of them.

: btw...2D skies?

Surelly you are aware that bryce has 2D skies. There is nothing really 3D about them (except for the altitude). They are simple 2D planes, and they have been 2D planes since Bryce1. And I personally think that sucks.

Regarding grass, this might be something that Corel will add in Bryce 6. I mean, (judging from the info on Corel's site) it's possible to create grass in Poser 5. We all have seem the impressive movie sequence with the ball and the hairy carpet, atleast I think we all have. :-)
You don't have to take a long peek in the bryce gallery to realize that post that include grass are greatly appreciated. I think this is what most Bryce users would prioritize in their B6 wishlist.

I fear that they will keep the old terrain objects and not bother creating a new system.
